A new sound-suppression study provides fresh insight for airfoil design and noise control for micro-aircraft and fluid machinery. The research focused on the concept of trailing-edge noise by using ...

Owl-inspired innovations can reduce noise by as much as 10 decibels, similar to the difference in noise between a passing truck and a passing car. Ed MacKerrow / In Light Of Nature Every owl fancier ...

The micro-fringes on owl wings effectively suppress the noise while maintaining the aerodynamic performance of the wings comparable to that of a wing without the fringes. Owls are fascinating ...

WASHINGTON, January 18, 2022 -- Trailing-edge noise is the dominant source of sound from aeronautical and turbine engines like those in airplanes, drones, and wind turbines. Suppressing this noise ...

Ms. Ackerman is the author of “What an Owl Knows: The New Science of the World’s Most Enigmatic Birds,” from which this essay is excerpted. When the first lucky observers spotted Flaco, the Eurasian ...

Silent Hunter: The animal known as the Silent Hunter is the owl, recognised worldwide for its completely noiseless flight, night-time precision, and ability to detect prey through sound alone. Owls ...
